一、電池片回收有什么作用

1、減少對環境的污染壓力

如今，隨著社會經濟的發展，社會環境正面臨嚴峻的考驗。一方面，不可生資源的數量正在減少。另一方面，一些污染現象還在不斷破壞環境的平衡結構。比如說部分人隨意丟棄廢舊的電池片。這種情況下(xia)，會對(dui)環境的土(tu)壤、水源等產生嚴重(zhong)危害。

2、提高資源的使用效率

廢舊電(dian)池(chi)(chi)片(pian)并不是沒有用(yong)途，其實，廢舊電(dian)池(chi)(chi)片(pian)可(ke)以被(bei)再(zai)次利(li)用(yong)，從而可(ke)以提高資(zi)(zi)源的使用(yong)效(xiao)率，尤其是一些(xie)不可(ke)再(zai)利(li)用(yong)的資(zi)(zi)源能夠(gou)(gou)得到較好的保護，既能夠(gou)(gou)延長資(zi)(zi)源的使用(yong)時限(xian)，還(huan)能降低部(bu)分物資(zi)(zi)對環境造成的污(wu)染。

3、節省了一定的生產成本

從電(dian)池(chi)片回(hui)收公(gong)司了解到(dao)，他們(men)使用廢舊電(dian)池(chi)為原料，生(sheng)產(chan)新的電(dian)池(chi)成本得到(dao)了大幅度降低(di)，實現了“雙贏”的局面。

在(zai)日常的(de)(de)工作(zuo)生(sheng)活中，建議(yi)大家要妥善處(chu)理好廢舊電(dian)池(chi)(chi)片，尤其是(shi)不(bu)能隨(sui)意處(chu)置，比(bi)如說丟棄在(zai)垃圾(ji)堆里(li)，那樣將會造成很大的(de)(de)危害，盡可能將廢舊電(dian)池(chi)(chi)片收(shou)集起來送(song)到(dao)電(dian)池(chi)(chi)片回收(shou)公司，在(zai)實現廢舊電(dian)池(chi)(chi)片回收(shou)的(de)(de)同時，對保護環境起到(dao)了很好的(de)(de)作(zuo)用。

三、太陽能電池片怎么進行回收

電(dian)池(chi)片可(ke)以回收，可(ke)以從太陽能(neng)電(dian)池(chi)中回收純(chun)硅。

太陽能電池主要含有硅（約91.6%重量）。它還包含其他材料，例如底層的鋁，頂層的銀電極，以及頂層的鉛和抗反射涂層。p型和n型硅晶片位于抗反射涂層和鋁層之間。太陽能電池片藍色層(ceng)是抗(kang)反(fan)射(she)涂層(ceng)（SiNx），白線是銀電(dian)極。太陽能電(dian)池片的底(di)部為(wei)鋁(lv)層(ceng)。為(wei)了去除(chu)這(zhe)些材料（鋁(lv)、銀、鉛和抗(kang)反(fan)射(she)涂層(ceng)），需使用(yong)化(hua)學處理方法(fa)。

首(shou)先(xian)，氫氟酸(suan)或氫氟酸(suan)與其他(ta)化學品的(de)混合物用(yong)于(yu)去(qu)除太陽(yang)能電池的(de)抗反(fan)射涂層、銀、鉛和(he)pn結。由于(yu)氫氟酸(suan)是(shi)劇毒和(he)腐(fu)蝕性化學品，因此在(zai)目前的(de)工作中不再使用(yong)氫氟酸(suan)。每一層都使用(yong)化學處理一層一層地去(qu)除。

用濃NaOH溶(rong)液處(chu)(chu)理(li)后去除鋁層。在(zai)反應過程中(zhong)形成的氫(qing)氣被收(shou)集在(zai)一個腔(qiang)室中(zhong)并(bing)可用作(zuo)燃料(liao)。通(tong)過過濾從NaOH溶(rong)液中(zhong)分(fen)離(li)氫(qing)氧化(hua)(hua)鋁。類似地，通(tong)過用HNO3處(chu)(chu)理(li)去除銀(yin)和鉛(qian)。收(shou)集釋放的NO2并(bing)可用于生產(chan)硝酸。分(fen)離(li)硝酸銀(yin)，溶(rong)液用HCl處(chu)(chu)理(li)，形成氯(lv)化(hua)(hua)銀(yin)。濾出沉淀(dian)的氯(lv)化(hua)(hua)銀(yin)。此外，將溶(rong)液用NaOH處(chu)(chu)理(li)以從溶(rong)液中(zhong)分(fen)離(li)鉛(qian)化(hua)(hua)合物（PbO）。氧化(hua)(hua)鉛(qian)轉化(hua)(hua)為(wei)氫(qing)氧化(hua)(hua)鉛(qian)，過濾沉淀(dian)的氫(qing)氧化(hua)(hua)鉛(qian)。
